TO INSTALL AND REPLACE BATTERIES IN THE PROJECTION CLOCK
The Projection Clock uses 3 x AA, IEC LR6, 1.5V
batteries. To install and replace the batteries, please follow
the steps below (the battery cover is located at the back of the unit):
1.
Using a finger or other suitable object in the space at the
bottom center of the battery cover and pull to remove.
2.
Observing the correct polarity, insert the batteries (see
markings inside the battery compartment).
3.
After inserting the batteries, replace the battery cover by
clicking into place.
TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace
the batteries, please follow the steps below:
1. Remove
the
cover.
2.
Insert batteries observing the correct polarity (see marking).
3.
Replace the battery cover on the unit.
SETTING UP
The Projection Clock can be either batteries-operated or powered by the provided AC-DC
adapter.
BATTERIES INSTALLATION
1.
Insert the 2 x AAA, IEC LR3, 1.5V batteries into the transmitter (See
“To install and replace batteries in
the Temperature Transmitter”
above).
2.
Within 3 minutes, insert 3 x AA, IEC LR6, 1.5V batteries into the Projection Clock (See
“To install and
replace batteries in the Projection Clock”
above). All the segments of the LCD will light up briefly and a
“beep” will sound. Then the time as 0:00, the indoor temperature, and the outdoor temperature as “ - -.-
ºC” will be displayed.
3.
The Projection Clock will now start receiving outdoor temperature signal. Once the remote temperature
has been received and is displayed on the Projection Clock, the DCF-77 time code reception is
automatically started. This takes typically between 3 - 5 minutes in good conditions. This time period is an
excellent opportunity to locate the transmitter in suitable location. In order to ensure sufficient 433 MHz
transmission however, this should, under good conditions be no more than 20 - 25 meters from where the
Projection Clock will be finally positioned (see notes on “
Positioning
” and “
Checking for 433 MHz
Reception
”).
4.
If after 10 minutes the DCF time has not been received, manually enter the time
.
The clock will
automatically attempt each hour to receive the DCF time. When this is successful, the received time will
override the manually set time. The date is also updated with the received time (Please refer also to notes
on “
DCF-77
Radio Controlled Time
” and “
Manual Time Setting
”).
Your Projection Clock is now operational!
Note:
If the batteries are used as the main power source:
1.
Projected image brightness, alarm volume and back-light strength would be weaker.
2.
Battery lifetime would be much less than 1 year.

TO USE THE PROJECTOR POWER ADAPTER
The unit comes with an AC-DC adapter for using the projector for an extended period of time, such as
throughout the night.
To connect the AC-DC adapter:
Important!
Make sure that your household voltage is 230V! Otherwise it can result in damaging your
Projection Clock.
1.
Insert the 2 x AAA, IEC LR3, 1.5V batteries into the transmitter (See
“To install and replace batteries in
the Temperature Transmitter”
above).
2.
Within 3 minutes, connect the AC-DC adapter to a wall socket. Plug the adapter into the jack at the
bottom of the Projection Clock. All the segments of the LCD and the projection will light up briefly; and a
“beep” will sound. Then the time as 0:00, the indoor temperature, and the outdoor temperature as - -.-
°C
will be displayed.
3.
The Projection Clock will now start receiving outdoor temperature signal. Once the remote temperature
has been received and is displayed on the Projection Clock, the DCF-77 time code reception is
automatically started. This takes typically between 3 - 5 minutes in good conditions. This time
period is an
excellent opportunity to locate the transmitter in suitable location. In order to ensure sufficient 433 MHz
transmission however, this should, under good conditions be no more than 20 - 25 meters from where the
Projection Clock will be finally positioned (see notes on “
Positioning
” and “
Checking for
433 MHz
Reception
”).
4.
If after 10 minutes the DCF time has not been received, manually enter the time
.
The clock will
automatically attempt each hour to receive the DCF time. When this is successful, the received time will
override the manually set time. The date is also updated with the received time (Please refer also to notes
on “
DCF-77
Radio Controlled Time
” and “
Manual Time Setting
”).
Your Projection Clock is now operational!
Note:
If the Projection Clock is powered through the AC-DC adapter, the projection will be constantly ON at the
highest brightness level unless the brightness level is manually changed to a lower brightness level afterward.
The brightness of the projection can be changed accordingly to enhance the clarity of the projected time by
pressing the key.
If the Projection Clock is battery operated, only when the SNOOZE key is pressed, the projection will turn ON at
its highest brightness level. The intensity of the brightness level of the projection cannot be adjusted. Once the
SNOOZE key is released, there will be no projection.
Important!
If the DCF-77 signal is not being received, no key functions can be used. In that case, either wait
for the next reception of the DCF signal or proceed to manual time setting after reset of the clock
for activation of the key function.
BATTERIES POWERED WITH THE USE OF AC-DC ADAPTER
If the Projection Clock is first powered by batteries and the AC-DC adapter is subsequently used for extended
period of time, the main power source of the Projection Clock will switch to AC power. The batteries will then act
as a backup power source in the case of power failure.

DCF-77 RADIO CONTROLLED TIME
The time base for the radio-controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig which has a time deviation of less than one second in every one million years.
The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and
has a transmitting range of approximately 1,500 km. The Projection Clock receives this signal and converts it to
show the precise time and so when within this range the received time is completely accurate.
CHECKING FOR DCF-77 RECEPTION
The Projection Clock will automatically start scanning for the DCF-77 frequency signal after the battery is
inserted. In normal surroundings (for example away from interfering sources such as TV sets), it takes between
3 - 5 minutes to receive the signal. If after 10 minutes of inserting the batteries into the alarm clock and the
DCF-77 signal is not received, then check the following list before manually setting the time (see
“Manual Time
Setting”
):
1.
The distance of the Projection Clock should be at least 1.5 - 2.0 meters away from interfering sources
such as computer monitors or TV sets.
2.
Avoid placing the Projection Clock onto or in the immediate proximity of the materials made of metal such
as doors, window frames or other structures.
3.
Within thick concrete rooms such as basements and tower blocks, the DCF-77 signal is naturally weaker.
In extreme cases, place the Projection Clock closer to a window and/or point its front or rear towards the
general direction of the Frankfurt/Main transmitter (avoid positioning within close proximity of metal
frames or structures).
Note:
Users may be located in areas where atmospheric disturbances are the direct cause for not receiving the DCF-
77 frequency signal. During nighttime, atmospheric disturbances are usually less severe and reception is
possible in most cases. With a single daily reception, it is adequate for the alarm clock to keep time deviation to
below 0.5 seconds in a period of 24 hours.
When the Projection Clock is trying to receive the DCF signal, the reception icon will flash on the LCD. Once the
signal is “locked”, the DCF-77 tower icon will stay fixed on LCD and the received time will automatically correct
the manually set time. As well as the time, the date will also be received by the Projection Clock and will be
displayed accordingly in the calendar section of the LCD.

WEATHER FORECAST AND TENDENCY
THE WEATHER FORECASTING ICONS:
There are 3 weather icons on the third section of the LCD, which can be displayed in any of the following
combinations:
Sunny
Cloudy with sunny intervals
Rainy
For every sudden or significant change in the air pressure, the weather icons will update accordingly to
represent the change in weather. If the icons do not change, then it means either the air pressure has not
changed or the change has been too slow for the Projection Clock to register. However, if the icons displayed is
a sun or raining clouds, there will be no change of icon if the weather gets any better (with sunny icon) or worse
(with rainy icon) since the icons are already at their extremes.
The icons displayed forecasts the weather in to terms of getting better or worse and not necessarily sunny or
rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it
does not mean that the product is faulty because it is not raining. It simply means that the air pressure has
dropped and the weather is expected to get worse but not necessarily rain.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours. This will allow
sufficient time for the Projection Clock to collect air pressure data at a constant altitude and therefore result in a
more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is
estimated to have an accuracy level of about 75% due to the varying areas the Projection Clock has been
designed for use in. In areas that experience sudden changes in weather (for example from sunny to rain), the
Projection Clock will be more accurate compared to use in areas where the weather is stagnant most of the time
(for example mostly sunny).
If the Projection Clock is moved to another location significantly higher or lower than its initial standing point (for
example from the ground floor to the first floor of a house), remove the batteries and re-insert them after about
30 seconds. By doing this, the Projection Clock will not mistake the new location as being a possible change in
air-pressure when really it is due to the slight change of altitude. Again, disregard weather forecasts for the next
12 to 24 hours as this will allow time for operation at a constant altitude.
THE WEATHER TENDENCY INDICATOR:
Working together with the weather icons are the weather tendency indicators (located on the left and right hand
side of the weather icons). When the indicator points upwards, it means that the air-pressure is increasing and
the weather is expected to improve, but when indicator points downwards, the air-pressure is dropping and the
weather is expected to become worse.
Taking this into account, one can see how the weather has changed and is expected to change. For example, if
the indicator is pointing downwards together with cloud and sun icons, then the last noticeable change in the
weather was when it was sunny (the sun icon only). Therefore, the next change in the weather will be cloud with
rain icons since the indicator is pointing downwards.
Note:
Once the weather tendency indicator has registered a change in air pressure, it will remain permanently
visualized on the LCD.

STORM WARNING:
When the air pressure drops continuously within a period of 8 hours, the “Rainy” icon will display; the
“TENDENCY” icon and the downward arrow will flash as an indication of possible storm. Flashing will stop when
the air pressure stays stable for the next 4 hours or when the air pressure starts to increase. The weather icon
might possibly be changed as the air pressure rises.
BACK-LIGHT
The back-light is automatically switched ON when any keys are pressed. The back-light will be switched on for
approximately 2 seconds before automatically switching OFF.
However, if any of the keys are pressed and held
down, then back-light will remain ON constantly until the key is released.
ABOUT THE OUTDOOR TEMPERATURE TRANSMITTER
The range of the Outdoor Temperature Transmitter may be affected by the temperature. At cold temperatures
the transmitting distance may be decreased. Please bear this in mind when positioning the transmitter. Also the
batteries may be reduced in power.
CHECKING FOR 433 MHz RECEPTION
If the outdoor temperature data is not being received within three minutes after setting up (the display shows
“- -. - °C” on the outdoor temperature section of the Projection Clock after 4 attempts), please check the
following points:
1.
The distance of the Projection Clock or transmitter should be at least 2 meters away from any interfering
sources such as computer monitors or TV sets.
2.
Avoid placing the temperature transmitter onto or in the immediate proximity of metal window frames.
3.
Using other electrical products such as headphones or speakers operating on the 433MHz-signal
frequency may prevent correct signal transmission or reception. Neighbors using electrical devices
operating on the 433MHz-signal frequency can also cause interference.
Note:
When the 433 MHz signal is received correctly, do not re-open the battery cover of either the transmitter or
Projection Clock, as the batteries may spring free from the contacts and force a false reset. Should this happen
accidentally then reset all units (see
“Setting up”
above) otherwise transmission problems may occur.
The transmission range is around 20 - 25 m from the transmitter to the Projection Clock (in open space).
However, this depends on the surrounding environment and interference levels. If no reception is possible
despite the observation of these factors, all system units have to be reset (see
“Setting up”
above).
POSITIONING
The Outdoor Temperature Transmitter has a holder and is supplied with screws and double-sided tape for
affixing by either method preferred. Before securing the transmitter to the desired location,
check that the
temperature can be received first.
TO AFFIX BY SCREW, FOLLOW THESE STEPS:
1.
Using the holes in the holder as a guide, mark the holes on the drilling
surface.
2.
Drill the marked area to the required depth.
3.
Screw the holder onto wall and click the transmitter into holder.

TO AFFIX USING DOUBLE-SIDED TAPE, FOLLOW THESE STEPS:
1.
Clean both surfaces before affixing double-sided tape.
2.
